In the heart of Berlin, Danish architecture firm 3XN has recently completed Cube Berlin, a striking new office showcasing the latest advances in sustainability, digitization and design. Opened this month, Cube Berlin also serves as a new city landmark with its sculptural, reflective facade designed to engage the pedestrian realm at the historically significant site of Washingtonplatz. The building is expected to achieve DNGB Gold certification and is engineered with smart office technologies that learn and adapt to user behavior to optimize comfort and energy efficiency.
Designed as a prismatic reinterpretation of the cube, the sculptural Cube Berlin measures 4.25 meters in all directions. Reflective glazing wraps around the exterior to mirror the surroundings and engage passersby while allowing natural light into the building without compromising privacy. The floor-to-ceiling windows frame stunning views of Berlin landmarks, and select operable openings let in natural ventilation. Solar coatings to the facade, described by the architects as an “osmotic skin,” along with external solar shading mitigate unwanted solar gain and ensure high energy savings.
In addition to providing visual interest, the reflective prismatic facade also provides opportunities for outdoor terraces on all levels. Outdoor space has also been created on the roof — the “fifth facade” — that features a spacious rooftop terrace shared by office tenants. The office building comprises 10 floors of flexible, multi-tenant office space as well as a ground-floor food market and office lobby, underground parking, plant rooms, conference areas and a rooftop terrace.
As a “next generation smart building,” Cube Berlin allows for greater interactivity between users and the building operations. Building operational information is stored in a “digital brain” server that collects data on energy flow and consumption. Users can use an app to interact with the system by remotely controlling features such as access control, indoor heating and cooling, maintenance, energy supply, room and parking reservations, charging of electric cars and bicycles and more.
“In this way, the building and its users enter into an interplay where both are learning from each other,” the architects explained. “The building learns to adjust to the preferences of its users, while the users can control and adapt the building’s settings according to their desires and needs.”
